What is a traction substation?
A traction substation is an installation within a railway or tram system designed to convert high voltage electrical energy from the main network to a lower voltage suitable for powering electric trains or trams. It typically houses traction transformers, as well as other essential equipment such as circuit breakers, switchgear and control systems. The substation plays a crucial role in ensuring a reliable and efficient supply of electrical energy to the traction network, thus enabling the operation of electric rail vehicles.
A traction transformer is a specialized type of transformer used in railway and tram systems to step down high voltage electrical power to a lower voltage suitable for traction motors and other railway systems. These transformers are designed to meet the unique requirements of railway environments, including vibration, thermal variations and electrical stresses. They ensure that electric trains or trams receive the appropriate voltage and current for efficient operation.
There are several types of substations, each performing different functions within an electrical system. These include:
Transmission Substations: Convert high-voltage electricity from power plants to higher voltages for long-distance transmission.
Distribution substations: Reduce high-voltage electricity to lower voltages suitable for distribution to residential and commercial users.
Switching substations: Facilitate switching of electrical circuits to manage power flow and maintain grid reliability.
Traction substations: Specifically used for railway and tram systems to provide power to electric trains and trams.

Converter substations: convert alternating current to direct current or vice versa, used in systems requiring different types of electrical energy.
What types of substations are there?
A substation is an integral part of an electrical power system used to manage and control the distribution of electrical energy. It generally includes equipment such as transformers, circuit breakers, switches and protective devices. The main purpose of a substation is to lower or raise voltage levels to meet the needs of different parts of the electrical system, to ensure the safe and efficient distribution of electricity and to ensure the control and protection of the electrical network.
A switching substation performs the function of directing the flow of electrical energy within the network. It contains equipment such as circuit breakers, switches and disconnectors that enable the routing and switching of electrical circuits. This type of substation helps isolate sections of the electrical system for maintenance, redirect the flow of energy in response to outages or outages, and ensure the reliability and stability of the electrical network by managing connections between the different parts of the network.
